New Cabbage Configuration

Introduction

The work of the Cheese Sauce Research Network has met with wild success, and its growth has been phenomenal. It

qualifies for address space (64.255.192.0/20) and an AS of its own (300). A special request was made for 300, in the

spirit of Charles deGaulle's comment "Any country with three hundred cheeses is ungovernable."

Because Broccoli still has funding for CSRN, CSRN will use Broccoli for its primary connectivity, with a backup link to

Cabbage. CSRN is physically in the same building as Broccoli, but will use the LAN previously assigned to Broccoli

CSRN applications as its access link to Broccoli.

In the first part of this lab, you will set up the environment before CSRN has its own router and AS number. In the

second part, you will convert to the new configuration. Figure Case 3 gives a high-level view:

Address assignments in this lab are not the most efficient possible, because the focus of the lab is not justifying

address space.

What changes need to take place on Broccoli, CSRN, and Cabbage, starting from the Case 3 configuration and

adding CSRN? Here are the current assignments of address blocks and AS numbers:
